I have 2.5" aluminum charge pipes and a precision intercooler with 2.75" inlet/outlets. I dont want to spend $50 on two reducer couplings so I was wondering if I can have the charge pipes expanded or will be "tear" because the aluminum piping is too thin?

 

I would assume that the aluminum would rip instead of expanding. By the time you get 2 2.75 couplers and pay someone to expand it, it should be around $50. I would just save the headaches and do it the right way.

ohhhh ok.....didnt think about it that way...thanks

 

depending on what type of aluminum it is, it could possibly crack as u try to expand it. I think heating it up will aviod this but i am unsure as to wat temp.

 

I've expanded some pretty cheap 16ga. aluminum up to a 1/4". It cracked any larger than that.

 

Heat it up nicely with a propane or map gas torch, and you should have no problem expanding the tubing. I've stretched 2.25" tubing to over 3" diameter when making velocity stacks.
